Roughness is defined as fine irregularities in the surface texture, which results from the inherent action of a production process. In protective coating applications there is a requirement to measure surface roughness to ensure a surface quality suitable for coating application.
Surface roughness measurements can also indicate processing stages that cause an increase in surface roughness, which may impact upon a products final suitability for application.
Aerofin Laboratories can conduct Surface roughness testing. testing specifications include:
